ADSP-21062LCS-160

Digital Signal Processor Dsp Overview

The ADSP-21062LCS-160 is a 32-bit floating-point digital signal processor from the Analog Devices SHARC family. It operates at a clock rate of 40 MHz, delivering 120 MFLOPS peak performance with a 25 ns instruction cycle. The device features 2 Mbits of dual-ported on-chip SRAM and supports both 32-bit single-precision and 40-bit extended-precision IEEE floating-point formats. It utilizes a Super Harvard architecture with four independent buses for simultaneous instruction fetch and data access. The component is housed in a 240-lead thermally enhanced MQFP package (MQFP_PQ4) and requires a 3.3 V core and I/O supply voltage.

Digital Signal Processor Dsp Feature Summary

• SHARC Core: 40 MIPS execution rate, 120 MFLOPS peak performance, single-cycle multiply/ALU operations.
• Memory Architecture: 2 Mbits dual-ported on-chip SRAM organized into two 1 Mbit blocks; supports 16-bit, 32-bit, and 48-bit word accesses.
• I/O Interfaces: Integrated Host Processor Interface (16/32-bit), six Link Ports, two 40 Mbps synchronous serial ports, and a 10-channel DMA controller.
• Multiprocessing: Glueless multiprocessing support for up to six processors via distributed bus arbitration and link ports.

Digital Signal Processor Dsp Applications

• High-performance communications systems requiring real-time signal processing.
• Graphics and imaging applications utilizing FFT and filter algorithms.
• Scalable DSP multiprocessing architectures for parallel computation tasks.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'S' against the official ordering guide to confirm the package type and temperature range, as suffixes define physical attributes. Confirm RoHS compliance status for the specific revision. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) prior to procurement, as older SHARC models may have limited availability or alternative recommendations from the manufacturer.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21062LCS-160 when 2 Mbits of on-chip memory is sufficient, distinguishing it from the 4 Mbit ADSP-21060 variants. Ensure the design accommodates the 3.3 V operating voltage, unlike the 5 V ADSP-21062. Verify that the 240-lead MQFP_PQ4 package footprint matches the PCB layout requirements, including thermal pad considerations for heat dissipation during sustained high-load operations.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2106x SHARC family, which includes the ADSP-21060, ADSP-21062, and their low-voltage (L) and commercial (C) variants. The 'L' designation indicates 3.3 V operation, while 'C' typically denotes commercial temperature ranges. The 'S' suffix in this part number specifically identifies the 240-lead MQFP package variant within the broader ADSP-21062L product line.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the age of the SHARC 2106x series. Consider the ADSP-21062LCZ-160 if a CQFP package is acceptable. For modern alternatives, evaluate the ADSP-214xx series (e.g., ADSP-21469) for improved performance and newer development tools, though these require significant hardware and software redesign.
